Belimo FSAFB24-SR-S Smoke/Fire Damper Control Actuator Proportional W/Switch 24V

The Belimo FSAFB24-SR-S is a 24V modulating damper actuator designed exclusively for smoke control applications. This electromechanical device offers features essential for safety and system integrity, including proportional control, a spring-return mechanism, and an integrated switch. A 0–10V control signal is converted into proportionate damper movement by the FSAFB24–SR-S. This makes it possible to precisely control the airflow, guaranteeing efficient smoke containment in the event of a fire. It offers precise airflow control depending on current conditions, facilitating effective smoke redirection and enhancing building security. The spring automatically closes the damper in the event of a power outage, limiting the flow of smoke and stopping it from spreading throughout the ventilation system. Even in emergency situations, smoke containment is maintained thanks to this vital fail-safe function.
